Barack Obama’s campaign has spent at least $2.8 million advertising on Google (GOOG) so far in 2008, by far the biggest chunk of $3.66 million spent on online advertising, according to Federal Election Commission filings reviewed by Clickz.
Here’s a monthly breakdown of online ad spending for the Obama campaign: $640,000 in January, $1.9 million in February, $888,000 in March and $234,000 in April.

It’s a tiny slice of the estimated $3 billion that will be spent on campaign-related advertising spending, and no data here on recent spending from Hillary Clinton and John McCain, but in past filings, Obama has far outspent his rivals online.
